1. To describe a novel surgical technique for managing late rhegmatogenous retinal detachment (RRD) and vitreous hemorrhage developing following successful retinoblastoma treatment. 2. To evaluate anatomical and visual outcomes
Children’s Hospital Los Angeles, Los Angeles, USA.
Retrospective consecutive interventional case series of eyes that underwent 3-port endoscopic clear corneal vitrectomy (Endo-CCV) following previous retinoblastoma treatment.
A total of 7 eyes of 6 patients were included. Indications for Endo-CCV were rhegmatogenous retinal detachment (RRD) with proliferative vitreoretinopathy (PVR) in 5 eyes, and vitreous hemorrhage without RD in 2 eyes. Mean age at retinoblastoma (RB) diagnosis was 1.5 years. Mean age at completion of RB treatment was 2.8 years. Mean interval between completion of RB treatment and Endo-CCV was 96 months (range 2-176). Mean follow-up was 18.9 months (range 12-29) Overall, the mean number of intraocular procedures was 2.3 (range 1-6), with 1 eye requiring more than 3 intraocular procedures. In the RRD group, partial or complete retinal reattachment was achieved in 60% (3/5) with silicone oil in situ. RB recurred in 1 eye without extraocular involvement, requiring enucleation and chemotherapy; this eye had 6 intraocular procedures. Excluding the enucleated eye, visual outcomes ranged from 6/60 to PL, with 3 eyes achieving better than PL vision.
Endoscopic clear corneal vitrectomy is a novel approach for managing late vitreoretinal complications following successful RB treatment. Majority of eyes achieve partial or complete retinal reattachment and navigational vision. The risk of RB recurrence appears to be relatively low.
